A Ku Klux Klan supporter who allegedly stabbed three counter-protesters over the weekend in Anaheim lives in San Francisco, according to police.

Anaheim police said Charles Donner, who lives in San Francisco's Marina District, acted in self defense at a planned Klan rally on Saturday.

The rally never happened because KKK supporters were met by an angry group of counter protesters. Three members were thrown to the ground, kicked and beaten as soon as they gout out of their car, while other members drove off.

KKK Grand Dragon Will Quigg said his arm is fractured after the alleged attack.
